  • Patent number: 6115251
    Abstract: An improved apparatus is disclosed for cooling the power dissipating components of a computer subsystem, including microprocessors and hard disk drive assemblies. The apparatus utilizes the computer subsystem's chassis or enclosure, by configuring it as a roll bond panel formed from two sheets bonded together to define a fluid channel therebetween. Various concentrated sources of power dissipation are mounted within the enclosure on special component panels that themselves define a fluid channel. A working fluid is disposed within the channels of the component panels and the enclosure panel. During operation, heat generated by the sources of power dissipation is transferred to the working liquid within the fluid channels of the component panels and, in turn, to the working fluid disposed within the fluid channel of the enclosure panel, for dissipation by convection.

  • Patent number: 5430611
    Abstract: A spring-biased heat sink assembly for a multi-chip module that has several integrated circuit chips on a substrate. Thermal paste provides a thermal connection between a heat sink and the chips. A beam spring applies pressure to the back side of the substrate, maintaining a constant force that urges the chips against the heat sink and avoids mechanical stress that would otherwise result from lateral motion of the chips such as from differential expansion. A flat flexible cable connects the module with other circuitry.

  • Patent number: 5396403
    Abstract: A heat sink assembly for a multichip module. A thermally conductive plate is bonded to integrated circuit chips on a multichip module by indium solder. The plate in turn is thermally coupled to a heat sink such as finned aluminum by thermal paste. The plate is made of a material such as silicon carbide or copper-tungsten alloy having a relatively low coefficient of expansion to minimize mechanical stress resulting from lateral motion of the chips due to thermal expansion. Relatively low-power chips may be thermally coupled to the plate by thermal paste instead of being bonded by solder.
